Solar PV divert
1. Normal (default):
- Charge at maximum current set by EVSE.
- If only solar PV feed available: charge rate is modulated based on solar PV generation.
- If grid +I/-E (positive Import / negative Export) feed is available: charge rate will be modulated by available excess power.
- If EVSE is sleeping: charging will begin when solar PV / excess power > min charge rate.
- Charging will not pause; this avoids excess wear on the EVSE relay and the EV.
SolarPV-gen topic:
Solar PV MQTT topic to modulate charge rate based on solar
Grid (+I/-E) topic:
Grid (+I/-E) MQTT topic to modulate charge rate based on excess power
OhmConnect
OhmConnect monitors real-time conditions on the electricity grid. When dirty and unsustainable power plants turn on, our users receive a notification to save energy.

MQTT config not configured with Solar PV / Grid topic.
Solar PV Divert requires the SolarPV-gen or Grid (+I/-E) MQTT topic to be defined on the Services tab.1. Normal (default):
- Charge at maximum current set by EVSE.
- If only solar PV feed available: charge rate is modulated based on solar PV generation.
- If grid +I/-E (positive Import / negative Export) feed is available: charge rate will be modulated by available excess power.
- If EVSE is sleeping: charging will begin when solar PV / excess power > min charge rate.
- Charging will not pause; this avoids excess wear on the EVSE relay and the EV.
Charging mode can also be set via MQTT:
{base-topic}/divertmode/set
Solar: Grid Import/Export: W - | Charge rate: A
